The horizontal rows of the table are called periods. The elements of a period are characterized by the fact that they have the same number of electron shells; the number of electrons in these shells, which equals the element's atomic number, increases from left to right within each period. ...
The alkali metal family includes the six elements in thefirst columnof the periodic table, fromlithium(Li) down to francium (Fr). These metals all contain one valence electron, meaning they form cations and react readily with water. These elements form the ionic bonds known as salts. Hydrogen...
Name an element in the third period (row) of the periodic table with three valence electron. Use the periodic table to give the name and symbol for each of the following elements: (a) the halogen in the same period as the alkali metal with 11 protons (b) the alkal...
What is a periodic table and how many groups of elements does it consist of? What group in the periodic table has the valence-shell configuration ns2np4? Which group in the periodic table contains elements with the valence electron configuration of ns^2np^1? Please explain!!
In the Periodic Table application you will find a huge amount of data about chemical elements for free. You will learn a lot of new and useful for yourself, no…
Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in t
In general, chemists and other scientists can use the table to predict how certain elements will react with one another. The alkali metals, for instance, are in the first column or group of the table and tend to have one valence electron and so carry a charge of +1. This charge means ...
